1 desmondwafers 8 months ago I just got a new 6120 that has a bigsby bridge, which I've never been a fan of. I want to put a tru-arc on it, but the spacing is different on the bigsby bridge. The newer pinned bridge gretsches have two little screws poking out of the top of the guitar that fit into recesses on the bottom of the bridge base. So the way I see it, I have two options: Remove the posts, fill the old holes and redrill them to the right spacing Get a new bridge base and attempt to drill out the tiny recesses on the bottom to fit the pins. Option 2 sounds worse, but I've never attempted anything like this before. Of course, I could just unscrew the pins and return it to floating, but I'd like to see if either of these options works first. If anyone's done something like this before, any help is appreciated!
